/* sprintf.c * * $Id$ * * Provides an implementation of the "sprintf" function, conforming * generally to C99 and SUSv3/POSIX specifications, with extensions * to support Microsoft's non-standard format specifications. This * is included in libmingwex.a, whence it may replace the Microsoft * function of the same name. * * Written by Keith Marshall * * This implementation of "sprintf" will normally be invoked by calling * "__mingw_sprintf()" in preference to a direct reference to "sprintf()" * itself; this leaves the MSVCRT implementation as the default, which * will be deployed when user code invokes "sprint()". Users who then * wish to use this implementation may either call "__mingw_sprintf()" * directly, or may use conditional preprocessor defines, to redirect * references to "sprintf()" to "__mingw_sprintf()". * * Compiling this module with "-D INSTALL_AS_DEFAULT" will change this * recommended convention, such that references to "sprintf()" in user * code will ALWAYS be redirected to "__mingw_sprintf()"; if this option * is adopted, then users wishing to use the MSVCRT implementation of * "sprintf()" will be forced to use a "back-door" mechanism to do so. * Such a "back-door" mechanism is provided with MinGW, allowing the * MSVCRT implementation to be called as "__msvcrt_sprintf()"; however, * since users may not expect this behaviour, a standard libmingwex.a * installation does not employ this option. * * * This is free software. You may redistribute and/or modify it as you * see fit, without restriction of copyright. * * This software is provided "as is", in the hope that it may be useful, * but WITHOUT WARRANTY OF ANY KIND, not even any implied warranty of * MERCHANTABILITY, nor of FITNESS FOR ANY PARTICULAR PURPOSE.
